WILLIAM F. BARNES AND JOHN BARNES, OF ROOKFORD, ILLINOIS.

BOOK-STITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,101, dated May 31, 1881.

Application filed April 30, 1880.

To all whom it may concern:

Beit known that we, WILLIAM F. BARNES and JOHN BARNES, of the city of Rockford, in the county ot' Winnebago and State of Illinois, have invented a new and useful Book- Stitching Machine, of which the following is a specification.

This invention relates to book or paper stitching machines in which wire is employed as a material of which to form the stitch; and the object of our invention is to 'produceamachine capable of taking the wire from the roll, spool, or other convenient package and cutting them from suitable lengths and inserting them in the folds of books or papers and ben ding them in such a manner as to securely tix the sheets in book form; and it consists in a carriage to receive the book or papers, capable of an automaticintermittin g endwise movement to present the matter vto be stitched in proper position to the stitching mechanism, and is made adjustablein its automatic movements to stitch at proper intervals books or papers varying in size, and is provided with an automatic disconnecting stop mechanism to permit the return movement of the carriage and stop the machine.

It consists, further, in a wirc-carryin g Inechanism made adjustable to present the wire in proper lengths to the bending, cutting, and driving mechanism 5 in Ia bending mechanism to give form to the wire to be driven through the book or papers; in a cutting and. driving mechanism to cut the wire from the continuous thread and drive it through the book or paper, and in abcnding and clinchin g mechanism to bend and clinch the'end ot' the wire driven through the book or paper.

These and other improvements to be hereinafter more fully explained constitute the subjectof this specin'caton.

In the accompanying drawings, Figure l is a plan view of a machine embodyingour invention. Fig. 2 is an under-face or bottomplan view, in which a portion of the centerhinged lever. is broken away to show the parts hinged to its upper face. Fig. 3 is a front elevation, in which some of the front parts are broken away to reveal the parts back thereof. Fig. 4 is an elevation of the left-hand end of the machine, in which a portion of the front edge of the table is broken away. Fig. 5 is a (Model.)

Fig. S is a vertical section on the dotted line y of Fig. 1, through the lengthwise center, of the wire-feedin g device, in which the wire bender, cutter, and driver are in their elevated position. Fig. 9 is a like vertical section yof a portion of' the same device on dotted line y of Fig. 1, in which the wire-benderis in its lowest position and the cutter and driver is elevated. Fig. l() is a like vertical section of' the same portion as Fig. 9 on dotted line y of Fig. l, in which both the bender and the cutter and driver are in their lowest positions. Fig. l1 is a horizontal section of the wire-feeding device on dotted line z of Fig. 3. Fig. l2 is an isometrical representation of the automatic stop-clutch mechanism. Fig. 13 is an isometrical representation of the machine as seen from the upper left-hand corner. Fig. 14 is an isometrical representation of the machine as seen from the under left-hand corner. Fig. l5v is an isometrical representation of a book stitched by our machine.

In the figures, A represents a bed-plate of suitable dimensions, rectangular in plan. B represents a foot-Han ge on its rearlright and left hand sides, fitted to receivej screws or bolts by which to Iix it in position to a suitable stand or table. From this foot-flange the bed-plate rises in box-like form, having edges O molded in ogee or cyma-recta form. Centrally from the rear portion ot' this bed-plate rise ears D, between which are pivoted the lever-arms E and F, of which E represents the bending-arm, and F the cutting and driving arm. These arms, toward their forward free ends, are gui-ded in their vertical movements by means of standards G, which rise from the forward portion of the bed-plate. These leverarms are each provided With a spring, a, xed to their under face, operating to. hold the free ends ofthe lever-arms elevated.

At H is represented a cam-shaft fitted to revolve in bearings in the upper portion of the standards Gr. On this shaft are mounted, to revolve therewith, the several cams I, J, K, L, and M, of which the cam I is employed to 'operate the bending-lever E, and the cam J to operate the driving -lever F, the cam K to operate beveled end Sliding bar N, the cam L to IOO operate the wire-feeding mechanism, and the cam M to operate the bending and clinching mechanism.

The forward end of thc bed is fitted with vertical guideways b on each front side corner, beveled from the front rearward inwardly. These guideways are received bylike beveled guideways c, depending from the inner lengthwise bar, O, of a skeleton metallic table-frame, made vertically adjustable on the beveled vertical guideways I) and c. In connection with the inner lengthwise bar, 0, this metallic skeleton table-frameis composed of an outerlengthwise bar, l), placed parallel to the bar 0, and connected on their under edges by bracketarms d, which rise on the outside of the bar P, to receive the outer portion, R, of the table, to serve as a support for the outer portion ofthe matter to be stitched by the machine.

The upper inner edges of the lengthwise metallic bars of the skeleton table-frame are grooved, as at c, to receive acenter portion, S, fitted to slide lengthwise therein freely, forming an endwise-movable carriage. This table is made vertically adjustable on its vertical beveled guideways by means of'an adjustingscrew, j', threaded in a depending ear, g, in such a manner that its end operates against the under portion of the table to raise or lower it as the screw is turned to the right or left. This adjustment of the table is important, to adapt the machine to the varying thicknesses of work to be stitched.

At T is represented the base-plate ot" the wire-feeding device, which is fixed on the lefthand front corner of the main bed-plate, and overlapping the inner lengthwise bar, 0, of thc table in such a manner that the edge of the book or paper to be stitched may be placed between it and the table, and by means of the vertical adjustability of the table the space may be regulated to receive the book or papers snugly. The front edge ofthe base-plate T is fitted with an upward-curving guide, T', employed to give a free entrance of the matter to be stitched to the space between the table and the base-plate. On this base-plate T is mounted the wire-feeding device, of which h is a tubular shaft fitted to slide lengthwise in suitable bearings rising from the base-plate. One side of this shaft, near the center of its length, is cut away to its centcr, at which point it is provided with a clasp, 7L', which embraces the shaft, having its end portions project therefrom, forming ears, between which is pivoted a lever-pawl, h, in such a manner that when its free end is in the position represented in solid lines at Fig. 1l its inner end will cramp the wire h", passed through the shaft against the side thereof with sufficient force to cause it to move endwise with the sha-ft, and when the pawl is in the position represented in the dotted lines the shaft will be free to move in the opposite direction without movin g the wire.

At is represented a spiral spring, connected with the tubular shaft and with the base-plate in such a manner that the contraction of the spring will produce the return movement of the shaft, which is adjustablylimited by means of the adjusting-screw located to receive the free end of the pawl on its return movement. The forward end of thebase-plate is fitted with a perforated guide, i", through which the forward end of the wire is passed to the bending, cutting, and driving devices.

At j is represented a collar, adjustably fixed to the upper end of a shaft, j', by means of a suitable set-screw. This collar is provided with a lever-arimj, which extends to engage the face of lthe cam L. To this collar is fixed a lever-arm, 7', having its free end extended and turned down to meet the free end of the lever-pawl h. From this arrangement itwill be seen that the revolutions ofthe cam L will impart an oscillatory movement to the leverarm j through its connection with the leverarm j, which will cause the tubular shaft h to move forward and carry with it the wire L'", from which to form the stitch, and the further movement of' the cam will permit the lever-arm j" to swing outward, which movement will permit the return movement ot' the tubular shaft by the action of the spiral spring, and during this return movement of" the tubular shaft the wire will be held by the bending-lever E, and the return movement of the tubular shaft will pass over the wire, which will be again caught by the lever-pawl, to be carried forward with the succeedingforward movement of the shaft. The vertical shaft j extends through its vertical support L, and to its lower end, under the bed-plate, is fitted with a leverarm, k', having its free end extending forward under the center endwise-xnoving carriage. To the free end of this lever-arm is pivoted a spring-actuated lever-pawl, k, adapted to engage the saw-toothed ratchet k", fixed to the under face of a bar depending from the under face of the carriage.

At l is represented a spring, wound round the depending end of the vertical shaft j in such a manner that its spring action will operate to retract the lever-pawl It, which rearward movement is limited by an adjustingscrew, l', to increase or lessen the movement thereof as the screw is turned farther in or out. This adjustment determines the distance of the intermitting movements of the carriage by means of its pawl-and-ratchetconnection therewith, to regulate the distance between the stitches, to adapt the machine to stitch books or papers differing in length, and to insert more orless stitches in the article to be stitched.

At l is represented a stop fixed transversely on the movable carriage ot' the table, to serve as a gage against which to place the end of the book when in position ou the table to be stitched, to cause the book or papers to move with the carriage. A suitable automatic shipping-arm, l, rises from the transverse stopgage to a proper height, having its upper portion bent to a plane parallel to the carriage,

` nut, lby which to clamp the rod to the 'table.

The outer end of this rod isprovided with an upturned hook end, m, to receive the end of the'table to limit its endwisc movement.

At a is represented a spring coiled on a suitable stud, n', fixed in any convenient position to the bed or frame. .A suitable link, n", connects the free end of the spring-arm u with the carriage in such a manner that the action of the spring will operate to produce the return movement ofthe carriage when the springactuated pawl 7c is disengaged from the sawtoothed ratchet. Bye this arrangement it will be seen that the en d wise movement oty the carriage may be regulated to move endwse any distance within thc-limits of-the devices, to adapt it to stitch books or other matter. to be stitched of various lengths. u

At o is represented a disk mounted to oscillate on a screw-stud support, o', extending laterally from the upper end of. the left-hand standard G. To this disk is pivoted a vertical moving arm,p, which extends'down through the bed-plate, having its lower end provided with a right-angled arm,p, fitted at its free end with an upturned wedge-formed arm, p, which in its upward movement engages the beveled vendstud,p", which projects from the under face of the pawl 7c in such a manner as to disengagc the pawl from the saw-toothed ratchet, as represented in dotted lines, to permit the return movement ot' the carriage by the action of the spring u, connected therewith. The vertical movement of this disconnecting device is made automatic by means ofthe lever-arm o", projecting from the front edge of the disk o, which, in the forward intermitting movements ot' the carriage, is raised by means of the shipping-arm l, the inclinedportion of which passes under the arm o and causes it to ascend the inclination toits summit, as represented in dotted lines, Fig. 4, to disengage the pawl from the saw-toothed ratchet, as hereinbefore stated.

That portion of the cam-shaft H extending through its standard-support on the right-h and f -side of the machineis .slotted lengthwise on est position. On the outer portion of this slot-v ted shaft is loosely mounted a toothed gearwheel, K, having. its hub notched inclutch form, as at r, to receive the uprising portion ot' the clutch-bar, to cause the sha-ft to revolve with the4 wheel to impart motion to the different parts of' the machine. When the leverarm o is elevated, as represented in dotted lines, Fig. 4, the disk will be moved to bring its periphery in position to depress the clutchbar to disconnect it from the clutch-hub, to permit the wheel to revolve on its shaft-bearing without imparting motion to the machine.

At K is represented a sliding bar titted to move endwisein a central groove in the upper face ot' the bed-plate and between the bending, cutting, and driving arms. This slidebar at its forward end is of such height as to pass snugly under the wire from which the stitch is formed as it passes from the perforated guide i". Immediately in f'ront of' the wire the forward end, s, of this slide-bar is beveled forward and downward at a suitable angle, so that in its rearward movement the driver will descend its inclined face. This slide is also provided with an upward-rising arm, s', adapted to meet the rear face of the cam K, employed to govern its endwise movements.

At s is represented a spring coiled on the stud sf, fixed to the' bed-plate, and its free end connects with the slide-bar in such amanner that its spring action operates to hold it in its forward position with its vertical arm in contact with the face of the cam.

The head e ot the bending-lever arm E is provided on its inner face or sidenext to the cutting and driving head, and directly opposite the perforation in the wire-guide i, with a vertical groove, t, fitted to receive the wire, when bent to a vertical position over the beveled end center slide, as at t', by the downward movement of the head, and serves as a guide to direct and hold the wire in a vertical position, and prevent bending thereof when being driven through the parcel to be stitched. This bending-headis also provided withapresser-foot, t, extending from its lower face forward, to overlap the book or parcel to be stitched, and when in its lowest position its pressure on the book serves to hohl the carriage during the return movement of the springpawl 7c" over the saw-toothed ratchet, and at the same time permits the return movement of the wire-feeding device over the wire while it is held by the bending-head.

The cutting and driving lever F is fitted with a driving and cutting head, t, having its under rear face beveled at an angle to correspond to the inclined forward portion ofthe sliding former or bar K', over which it is placed, and is provided on its cutting-edge with a depending lip, which produces a slightly-curved drivin g-face provided with atransverse groove, u, adapted to receive the horizontal portion of the bent wire which overlaps the sliding bar, and in itsdownward movement between the ros IZO

ISO

bending-head and perforated wire-guide cuts the portion to form the stitch from thc main thread as it passes the perforation, and in its onward movement over the receding beveled end of the former or bar Ii drives the vertical arm through the book or parcel, and in the passage of the vertical arm through the parcel its end comes in cont-act with the inclined corner surface u of the opening in the inner bar of the table, which seri es to give it an inclined cnrving form.

At W is represented a lever-arm, hinged at its rear end to the rear end of the bed on its under side, and its forward end is pivoted to the rear barofthe table in such a inaniicrthatit will move with the vertical movements thereof. This lever-arm is provided with ears ii, rising from its sides, and receiving a transverse shaft, a", on which is pivoted a clincher consisting of a transverse bar, te, fitted to oscillate on the pivot-shaft, and from this transverse bar rises a vertical arm, 1i", Fig. 5, to meet the rear face of the cam M.

At te is represented a elinchingfarin, which extends horizontally from the front face ofthe transverse bar 1e, having its free end turned upward to freely enter an opening in the rear bar of the table, immediately under the driver. The upturned end of this clinching-arin is formed into a head, fc4, fitted to receive the driven end of the stitch in such a manner that in connection with the driver the stitch will be snugly clinched, having its free ends turned inward and embedded iii the book or parcel stitched. This clincher being mounted on the hinged lever pivoted to the table, its relative movements therewith will remain unchanged in the vertical adjustments of the table.

At 10' is represented a spring coiled on the transverse bar 1r, the action of which operates to hold the vertical arm 0f the clincher in contact with the cam and the clinching-head in its lowest position.

At XV' is represented a band-wheel, to the hub of which is fixed a pinion, W, both of which are lnouiited to revolve on a suitable bearing in such relative position to thc toothed gear-wheel K on the cam-shaft that the teeth of the pinion shall engage the teeth of the wheel on the cam-shaft. This band-wheel is designed to be pnt in connection with a prime mover by a suitable belt-connection to impart motion to the machine.

From the foregoing it will be seen that with a bool; or other parcel placed in position on the carriage, and a suitable wire threaded in the machine, the several parts properly adjusted,and motion imparted to the machine through the baiid-wlieel connection therewith, the wire will be carried forward a proper distance, bent at right angles, cnt from the thread, driven through the parcel, and properly clinched, and the parcel moved to a second proper position and again stitched in the same manner, which operation will be repeated automatically until the stitching of the parcel is completed, when as these maybe varied to meet the views ot' the designerortheeonvenienceof the mechanic in constructing the machine. As an instance, the beveled guideways, on which the table is made vertically adjustable, may be dispensed with, and the table may be provided with rigid arms extending to the rearward portion ofthe frame and pivoted thereto, to permit of a sufficientvertical movement, and in this construction the clincher may be mounted on a rearward extension ofthe table. These and man3v other mechanical changes may be employed without departing from the main features of our invention.
